PAST AND FUTURE REFERENCE-CALENDAR.

Application filed August 9, 1919. Serial No. 316,397.

To all whom it may concern:

Be it known that we, WILLIAM H, Rlons, Jr., and WALTER MEISENBAOH,citizens of the United States of America, residing at.

Hysham, in the county of Rosebud and State of Montana, have inventedcertain new and useful Improvements in Past and FutureReference-Calendars, of which the following is a specification.

This invention relates to past and future reference calendars and it hasfor its object the provision of a simple and inexpensive device of thecharacter referred to by means of which it will be possible to readilydetermine what day of the week any particular day fell upon throughoutthe past or will fall upon throughout the future either under the oldstyle or Julian calendar, or under the new style oar-Gregorian calendar.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

The figure shown in the accompanying drawing is an elevation of acalendar constructed and arranged in accordance with the invention.

Referring to the drawing 5 designates a card constituting the body ofthe calendar and 6 and 7 designate swinging sections pivotally connectedto the card 5 by means of eyelets 8 and 9, and having their confrontingends curved at 10 and 11 upon arcs of circles struck from the centers ofthe eyelets 8 and 9. The swingingly mounted or pivoted section 6 bearsmatter adapting this section to co-aet with the remainder of of thecalendar to determine dates under the old style or Julian calendar,while the pivoted section 7 bears like matter adapting. that section toco-act with the remainder of the calendar to determine the date underthe new style or Gregorian-calendar. In each case the section carries aplurality of arcuate columns of figures 12 which in conjunction withradial rows 13 constitute spaces 14 within which are printed numeralsfrom 1 to 100 indicative of the years of the I century. Each pivotedsection 6 or 7 also carries one or more hands or pointers 15, theposition to which said hand is to be set being determined by symbols 16set opposite and alined with figures 17 indicative of the severalcenturies.

The body of the calendar comprises a plurality of arcuate columns 18intersected by lateral rows 19 to constitute spaces which receive thenames of the months of the year I The colas indicated at 20 for example.

'umns 18 are subdivided by flaring lines 21 to form a plurality ofsmaller columns 22 Specification of Letters Patent. Patgnted Feb. 10, J

in which appear the names of the days Of the week as indicated at 23.These columns 22 are further divided laterally to form spaces 21 for thereception of numerals indicative'of the days of the month.

Inaddition to the foregoing, arcuate columns 25 and 26 are formedadjacent the curved front edges of the sections-6 and 7, and''concentric therewith, in which appear symbols 27 corresponding to thesymbols 16, and with which the hands 15 are adapted to co-act.

, Themethod of use of the device is as fol lows ' Assuming thatit isdesired to find what dayof the week the 31st day of May 1919,

will fall upon, reference is made. to the century. table of theGregorian calendar upon the pivoted section 7 and it will be found thatthe symbol C, among the symbols 16 appears opposite the years 1901 to2000. swung to such a position as to bring the hand 15 opposite thesymbol C in column 26, this willbring the numeral 19, indicative oftheyear 1919 in alinement with that lat.-

,eral row containing the names of the months, that we havespecially'designated X for the purpose of this explanation. Followingthis row across it will be found that the month of May occurs in thethird column from the right and by referring to the monthly calendar atthe top of this column it will be observed that the 31st day, there of,falls on Saturday.

In addition to the hands 15 we have prois to be used in lieu of the hand15 for de- This pivoted section is thenvided upon the Gregorian calendara symbol termining the proper positioning of the section 7 in findingdays occurring in leap years, and it will be observed that the names ofcertain ofthe months in the column l8 and throughout certain of the rows19 appear in heavier faced type than is the case with like namesappearing in the other rows and this is for the purpose of indicatingleap years. i 7

It will be noted that hands 15 appear at both-the upper and lowerportions of the sections 6 and 7, and either of these. hands It is to beunderstood that the invention is not limited to the precise constructionset 7 may be used according to whether the year of the century is foundadjacent to top of the section or adjacent to the bottomthereof. Weprefer to indicate the leap years in the Gregorian calendar with somedistinctive mark, such for vfrom theprinciples involved.

Having described our invention what we cla'irn is In a perpetualcalendar a body portion having a plurality of arcuatecolumns bearing thenames of-the months of the year arranged in rows transversely of all ofsaid columns and a monthly calendar relating to each of said columns, amember pivoted to said body portion to swing upon the arc example as thestar shown of a circle over the face thereof, said memher having itsfree edge formed concentrically with the pivot point and the outermostof said arcuate columns being concentric with the said edge, said memberand said body portion having cooperating indicia to,

indicate where the movable member is to be set with respect to the bodyportion, said member having transverse rows of figures relating to theyears of the century, the arrangement of said figures and the arrangement of the names of the months'being such, that when the movable memberis set with relation to the body portion in accordance with the indicia,the row of figures relating to the'years of the century in which theyear concerned appears, will aline with that row upon the body portionbearing the name of the month concerned, in that columnthat is relatedto the monthly calendar adapted to give the information sought.

In testimony whereof we aflix our signatures in the presence of twowitnesses.
